This paper presents an approximated DVDFB control by a strictly proper controller using the displacement output for large space structures with sensors/actuators collocation. The control law consists of a second order filter and PD feedback of the measured displacement. The second order filter is connected at each control input channel in order to make the controller strictly proper. It is shown that the closed-loop system becomes stable and optimal for a frequency-dependent quadratic cost function by choosing the filter parameters and the feedback gains appropriately.
